(At least around here) NAPA auto parts stores can mix automotive paint and put it in an aerosol can for you. Just make sure you're holding onto something solid when they quote the price.
US Coast Guard requires differently colored lights on the bow (red to starboard & green to port) on powered boats and a white light on the stern but I've always thought that was primarily so you could quickly determine which direction the boat was traveling (which is really important in bass...
That appears to be a pretty steep grade & I've been known to portage in that manner on steep hills or on swampy ground. I'll agree that it's not ideal though... If he'd left his gear in the boat, he'd only have to climb the hill (or struggle through a swamp) once.

I can count on one hand the number of people around whom I'd like to be 24/7 for several days / weeks at a time. Happily, none...
From your description, it seems to me like it will work...
I can't really help with your original question but can you install a hitch on the car? It's pretty simple to build a t-post to insert in a hitch and you can get much better separation that way. I have about 9 feet between the cross...

One of my best friends will tell you how to build a clock if you ask what time it is... you are not alone. ;)
